Metrodora
Simo is the founder of Metrodora Institute and President of the Metrodora Foundation. The institute opened its doors in April 2023 in Salt Lake City, Utah.

The Institute “aims to accelerate cures for neuroimmune disorders by reimagining how patients are treated, and how they participate in research.” The Institute has $35 million from an undisclosed venture investor. The Institute both conducts research and treats patients. It has a particular interest in interdisciplinary work, breaking apart the silos of current medical practice.

The Metrodora Institute welcomes those suffering from diseases that many doctors fail to diagnose, and often do not know how to treat.

Simo was motivated to start this medical venture by her own experience.

The name of the institute is from ancient Greece: “Metrodora was a Greek physician who wrote a medical text, most likely titled “On Women's Diseases,” in the late fifth century C.E., which is thought to be the oldest surviving medical text by a woman.”
